Abstract
Embodiments of the present application provide a method and a device for constructing an encoding sequence. The method comprises: storing a reliability sequence corresponding to a basic sequence, the length of the reliability sequence corresponding to the basic sequence being less than or equal to the length of a reliability sequence corresponding to a mother code sequence; storing a reliability reference sequence, the reliability reference sequence comprising, excluding the reliability sequence corresponding to the basic sequence, at least one element in the reliability sequence corresponding to the mother code sequence; and constructing an encoding sequence using the reliability sequence corresponding to the basic sequence and an element in the reliability reference sequence. By implementing the present application, only a reliability sequence corresponding to a basic sequence and a reliability reference sequence are stored when storage is performed. Because the total length of the reliability sequence corresponding to the basic sequence and the reliability reference sequence is far less than the length of an original reliability sequence, storage overhead can be reduced.

max的值,因此大大减小了存储开销。在读取的过程中,通过对该参考序列进行扩展或者多次读取,获得可靠度高的子信道集合;扩展或多次读取的方式与可靠度序列的类型相关。
The length N s of the reliability sequence corresponding to the basic sequence is smaller than the length N max of the reliability sequence corresponding to the mother code sequence, and the reliability reference sequence holds several elements capable of characterizing the reliability sequence corresponding to the mother code sequence, which may use Can also be used It is shown that the reliability reference sequence is only l max -l s in length. Therefore, when storing, it is only necessary to store only N s + (l max -l s ) values, which is much smaller than the value of N max , thus greatly reducing the storage overhead. In the process of reading, by expanding or multiple reading the reference sequence, a highly reliable subchannel set is obtained; the manner of expanding or multiple reading is related to the type of the reliability sequence.
具体的,若存储的基本序列对应的可靠度序列长度为
则根据PW序列的计算公式
其中,(i)
dec@(B
n-1B
n-2...B
0)
bin,再存储
等 可靠度参考值组成的序列
即能够完整表示出长度为N
max的母码序列对应的可靠度序列。
Specifically, if the stored basic sequence corresponds to a reliability sequence length of Then according to the calculation formula of the PW sequence Where (i) dec @(B n-1 B n-2 ...B 0 ) bin , then store Sequence of equal reliability reference values That is, the reliability sequence corresponding to the mother code sequence of length N max can be completely represented.
基于此,在构造编码序列,例如polar码序列的时候,根据需要构造的polar码的长度,读取所述存储的长度为
的基本序列对应的可靠度序列,并根据可靠度参考序列中的元素的值,对长度为
的基本序列对应的可靠度序列进行扩展或者进行多次读取,选择K
info+K
check个除打孔比特外可靠度最高的信息比特序号集合
其中,K
info为信息比特数量,K
check为校验比特数量,校验比特包括但不限于CRC比特和动态校验比特,K
check≥0。然后将对应的信息序列和动态校验比特序列(如果有)映射到这些序号;剩余的为静态冻结比特序号集合,其值设置为收发两端约定的固定值。
Based on this, when constructing a coded sequence, such as a polar code sequence, the length of the stored memory is read according to the length of the polar code that needs to be constructed. The basic sequence corresponds to the reliability sequence, and according to the reliability, the values of the elements in the reference sequence are The reliability sequence corresponding to the basic sequence is extended or read multiple times, and K info +K check is selected to have the highest reliability information bit number set except the punch bits. Where K info is the number of information bits, K check is the number of check bits, and check bits include but are not limited to CRC bits and dynamic check bits, K check ≥ 0. Then, the corresponding information sequence and the dynamic check bit sequence (if any) are mapped to the sequence numbers; the rest is a set of static freeze bit numbers, and the value is set to a fixed value agreed upon at both ends.
后续的实施例的举例中,以首先获得信息比特序号集合为例进行说明,先获得冻结比特序号集合,然后再取其补集获得信息比特序列结合原理相同,不再赘述。In the example of the following embodiment, the information bit number set is first obtained as an example for description. First, the frozen bit number set is obtained, and then the complement is obtained to obtain the information bit sequence. The principle of the combination is the same, and details are not described herein.

It can be seen from Table 2 and Table 3 above that only the reliability sequence or the reliable quantized sequence corresponding to the quantized basic sequence is stored. Values, storing the quantized reliability reference sequence or the reliability reference quantization sequence needs to store l max -l s =9-3=6 values, and only need to store 8+6=14 values in total, therefore, compared with the original Need to store 512 values (Table 1), can save (512-14) / 512 = 97.3% of storage space, greatly reducing storage overhead and improving storage efficiency.

由上述公式得到的可靠度参考序列如表13所示:The reliability reference sequence obtained by the above formula is shown in Table 13:
表13Table 13
256256 |
16501650 |
由上述表12和表13可知,存储可靠度序列时只需要存储
个值,存储可靠度参考序列值需要存储l
max-l
s=9-8=1个值,总共只需要存储256+1=257个值,因此,相比原可靠度需要存储512个值而言(表1),能够节约(512-257)/512=49.8%存储空间,大大减小了存储开销,提高了存储效率。
As can be seen from Table 12 and Table 13, the storage reliability sequence only needs to be stored. Value, storage reliability reference sequence value needs to store l max -l s =9-8=1 value, only need to store 256+1=257 values in total, therefore, it needs to store 512 values compared to the original reliability. Words (Table 1) can save (512-257) / 512 = 49.8% storage space, greatly reducing storage overhead and improving storage efficiency.
二、对于最大母码长度
的最大母码长可靠度序列,设置β=2
0.25,按照现有技术的存储方式,对序列值进行14bit量化,将存储1024个值,如表14所示:
Second, for the maximum mother code length The maximum mother code length reliability sequence is set to β=2 0.25 . According to the storage method of the prior art, the sequence value is 14-bit quantized, and 1024 values are stored, as shown in Table 14:

应用本申请提供将长度为1024的母码序列对应的可靠度序列变换为基本序列对应的可靠度序列加可靠度参考序列的实现方式,可以有如下几种:The application provides a method for converting a reliability sequence corresponding to a mother code sequence of length 1024 into a reliability sequence corresponding to a basic sequence and a reliability reference sequence, which may be as follows:
(1)设置l
s=3,N
s=8,PW
i,0≤i<8,由上述公式可以得到基本序列对应的可靠度序列,并且对其中的值按照14bit进行量化后,得到的量化后的基本序列对应的可靠度序列如表15所示:
(1) Set l s = 3, N s = 8, PW i , 0 ≤ i < 8, the reliability sequence corresponding to the basic sequence can be obtained by the above formula, and the obtained value is quantized according to 14 bits. The reliability sequence corresponding to the following basic sequence is shown in Table 15:

由上述公式得到的量化后的可靠度参考序列如表16所示:The quantized reliability reference sequence obtained by the above formula is shown in Table 16:

由上述表15和表16可知,存储量化后的基本序列对应的可靠度序列时只需要存储
个值,存储量化后的可靠度参考序列值需要存储l
max-l
s=10-3=7个值,总共只需要存储8+7=15个值,因此,相比原来需要存储1024个值而言(表14),能够节约(1024-15)/1024=98.5%的存储空间,大大减小了存储开销,提高了存储效率。
It can be seen from Table 15 and Table 16 above that only the storage of the reliability sequence corresponding to the quantized basic sequence needs to be stored. Values, storing the quantized reliability reference sequence value needs to store l max -l s =10-3=7 values, and only need to store 8+7=15 values in total, therefore, it is necessary to store 1024 values compared to the original value. In terms of (Table 14), it can save (1024-15)/1024=98.5% storage space, greatly reducing storage overhead and improving storage efficiency.
(2)设置l
s=4,N
s=16,PW
i,0≤i<16,由上述公式可以得到基本序列对应的可靠度序列,如表17所示:
(2) Set l s = 4, N s = 16, PW i , 0 ≤ i < 16, and the reliability sequence corresponding to the basic sequence can be obtained by the above formula, as shown in Table 17:

由上述公式得到的可靠度参考序列如表18所示:The reliability reference sequence obtained by the above formula is shown in Table 18:

可靠度序列也可以是原可靠度序列PW
i的有限精度量化值,只要量化后的可靠度序列仍满足与原可靠度序列相同的相对大小关系。
The reliability sequence may also be a finite precision quantized value of the original reliability sequence PW i as long as the quantized reliability sequence still satisfies the same relative size relationship as the original reliability sequence.
如可对表17和表18进行14比特量化
其中PW
i为量化前的PW序列,
为量化后的PW序列,max{PW}为量化前PW序列的最大值,
为向上取整函数,量化精度为14比特。量化后得到表19和表20。量化精度与母码序列的长度N
max成正相关,对越大的N
max,通常需要更大的量化精度,来确保量化后的母码序列对应的可靠度序列仍满足与原可靠度序列相同的相对大小关系。这里仅为举例,其他长度的母码序列的可靠度序列的量化方式原理相同,不再赘述。
For example, 14-bit quantization can be performed on Table 17 and Table 18. Where PW i is the PW sequence before quantization, For the quantized PW sequence, max{PW} is the maximum value of the pre-quantization PW sequence. For the rounding up function, the quantization precision is 14 bits. After quantification, Tables 19 and 20 are obtained. The quantization precision is positively correlated with the length N max of the mother code sequence. For a larger N max , a larger quantization precision is usually required to ensure that the reliability sequence corresponding to the quantized mother code sequence still satisfies the same original reliability sequence. Relative size relationship. Here, for example only, the quantization method of the reliability sequence of the mother code sequences of other lengths has the same principle and will not be described again.
